Application filed August 21, 1920. Serial No. 405,105.

To all whom it may concern:

Be it known that I, ALANSON P. BRUSH, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented acertain new In the drawing, Fig. 1 is a side elevationof a bearing in which the invention is em-' bodied, a part of the two bearing rings and of the cage ring being broken away; Fig. 2 is a section of the bearing in a plane indicated by line 22 on Fig. 1, and Fig. 3 is a radial section through one side of both bearing rings showing them in the relation they occupy, and showing the manner in which. the rollers may be introduced into operative position.

The raceway includes'an outer bearing ring 10,- and an inner bearing ring 15, the latter ring being disposed coaxially within the outer ring. In the outer periphery of the inner ring is a continuous annular V groove 12 which forms the inner raoeways for the rollers to be presently referred to.

I In the inner peripheryof the outer ring is while the line ofperipheral contact between an opposed annular groove 16, which forms the outer raceways for said rollers.

A plurality ofinclined anti-friction rollers 20 are disposed at equal distances apart,

around the axis o'f-the rings. Each roller extends across the annular. space between the rings, and has peripheral enga ement with the raceways in both rings. 11 the best construction, as shown, these rollers are inclined to such a degree that the line of peripheral contact between each roller and the raceway of the inner ring lies at one side of a plane, indicated by AB in Fig. 2, which is normal to the axis of the rings;

the rollers and the raceway in the outer ring lies wholl on'the opl' osite side of said plane. The. a tomato r0 ers are. similarly inclined in one direction, while the intermediate rollers are similarly inclined in the opposlte direction. One set of rollers, therefore, supports half of theradial load and end thrust or axial load in while the other-setof rollers the axial loador end thrust opposite direction.

The drawing'showswhat is now believed to be the best embodiment of this invention. In that construction, each of the rollers is an equatorial section of a sphere. The raceway grooves in the opposed faces of the two bearing rings, In radial section, are in'the tending in the form of arcs of a circle'having substantially the same radius. I

In order to assemble the rollers in oper-v ative position between the two bearing rings, these rings are first placed in coaxial relation as described. Then, as shown in Flg. 3, a roller is introduced edgewise into the annular space between the two rings, and is then ,twistedaround its own, axis until its ed es enter the two .curved race ways,--at w ich'time the roller 'will have peripheral engagement with the raceways in both rings. The rollers, as they are so introduced are alternatelyinclined in op-' posite directions as shown.

The rollers are kept in spaced relation by -a cage ring 30 which lies and is freely mov-.

ablein the annular space between the two bearing rings; and it contains recesses 31 in WllICh the rollers are loosely fitted, and

one direction, supports half from which they project for engagement, as

described, with the raceways in the bearing ,rings. The cage ring as shown is formed of two halves 30 30 ,and the roller holding recesses are formed in the meeting faces of these halves.

Having described my invention, I claim ,1 v 1. An anti-friction ring bearing conipris ing, in combination, an outer bearing ring,

and an inner bearing ring arranged coaxially within the outer bearing ring, which bearing rings have in their opposed cylindrical surfaces continuous raceway grooves, a

row of anti-friction Qro'llers which extend across the annular space betweenthe rings clined positions specified comprising a cage and have peripheral engagement with the raceways of both rings, said rollers beingraceways of both rings, said rollers being alternately inclined in opposite directions with respect to a plane normal to the axis of said rings, and a cage ring which is freely movable in the annular-space between said rings and is formed with alternately dis osed oppositely inclined recesses in whic said rollers are confined and loosel fitted.

3. Kn anti-friction ring bearing comprising, in combination, an outer bearing ring, and an inner bearing ring arranged coaxially within the outer bearing ring which bearing rings have in their opposed cylindrical surfaces continuous raceway grooves, a row of anti-friction rollers which extend across the annular space between rings and have peripheral engagement with the raceways in both rings, said rollers being alternately inclined in opposite directions with respect to a plane normal to the axis of said rings, the inclinations of said rollers being such that the lines of contact between the periphery of each roller and the raceways of the two rings lie on opposite sides of said plane, and means to maintain said rollers in spaced relation and in the inclined positions specified and a cage ring which is freely movable in the annular space between said rings and is formed with alternately disposed oppositely inclined recesses in which said rollers are confined and loosely fitted.

a. An anti-friction rlng bearing comprismg, in combinatlon, an outer bearing ring,

and an inner bearing ring arranged co-- circle above mentioned, which rollers extend across the annular space between the rings and have peripheral engagement with the raceways in both rings said rollers being alternately inclined in opposite directions with respect to a plane normal to the axis of said rings,and means to maintain said rollers in spaced relation and in the inclined positions specified.

5. An anti-friction ring bearing comprising, in combination, an outer bearing ring, and an inner bearing ring arranged coaxially within the outer bearing ring, which bearing rings have in their opposed cylindrical surfaces continuous raceway grooves which in radial section are arcs of the same circle, a row of anti-friction rollers each of which\ is an equatorial segment of a sphere having substantially the same radius as the circle above mentioned, which rollers extend across the annular space between the rings and have peripheral engagement with the raceways in both rings said rollers be ing alternately inclined in opposite directions with respect to a plane normal to the axis of said rings, a cage ring which is freely movable in the annular space between the rings and which is formed of two connected halves,-the meeting faces' of which lie substantially in the above mentioned plane normal to the axis of the ring, and said meetin faces being formed with recesses inwhich said rollers are confined and loosely fitted.

In testimony whereof, I hereunto afiix my signature.

ALANSON P. BRUSH.
